For whatever their reasons, nearly half the adults in the United States are saying they want nothing to do with the swine flu vaccine.

But two of three American adults told pollsters they were nevertheless concerned about the virus that has stuck 25,000 in this country and killed 114 children.

That’s according to a poll done by McClatchy Newspapers and published Tuesday.

And, the poll found, if people are skeptical about the vaccine, most aren’t blaming the Obama administration. Two out of three said they were confident that the administration had done everything in its power to make the vaccine available in time.
